Sam Moore’s path into sport science is defined by taking risks and chasing meaningful questions. After a devastating knee injury as a collegiate athlete, Moore not only returned to compete, but she also discovered her calling in strength and conditioning. She recounts her coaching, sport science, and hybrid roles prior to leaving a full-time position to pursue her PhD at the University of North Carolina at Chapel Hill. Moore describes sport science as problem-solving and drawing evidence across disciplines to drive innovation. She discusses her research on female athlete availability in elite settings, including nuances like body composition, recovery, and high speed exposure in training. Moore advises young professionals to remain open-minded, pitch their ideal position if it does not exist, and go “all in”— knowing one decision does not define forever. Whether you are a coach or researcher, this episode delivers real-world insights on navigating your career with courage and curiosity.
